LUBRICATORFOR L jOO'SE PU LLEYS.

SPECIFICATION forming part of Letters Patent N o. 455,368, dated July*7, 1891.

I Application filed August 7, 1890. Serial No. 361,358. (No model.)

To all whom t mag/concern- Be it known thatI, JOHN J. TUNNEY, a citizenof the United States, residing at Pittsburg, in the county of Alleghenyand State of Pennsylvania, have invented certain new and usefulImprovementsinLubricatorsforLoosePulleys; and I d-o hereby declarelthe following to be a full, clear, and exact description of theinventiomsuch as will enable others skilled it pertains to make and usethe same, reference being had to the accompanying drawings, which form'a part of this specification i My invention relates to an improvedlubricator for loose pulleys; and it consists in certain details ofconstruction and combination of parts, as will be fully describedhereinafter.

In-the accompanying drawings, Figure l is zo a side sectional elevationof my improved lubricator, showing the same attached in position on thehub of an ordinary loose beltpulley. Fig. 2 is a sectional plan view ofthe same. Fig. 3 is a side elevation of an adjustable post, being amodified means for attaching the To put my invention into practice withthe hub of a loose pulley of ordinary construction, I provide a vessela, spherical in shape 3o and having a hollow conical-extension b at itsbase, which extends downward and projects into an opening c, formed inthe hub d and leading to the shaft e, on which the pulley operates. l

f designates a rod attached to suitable braces or cross-rods in theupper portion of the vessel a, and a ball o1" sphere g is loosely fittedthereon, so as to be free to move along the rod, and it is adapted toclose the orifice 4o g', formed by the conical extension b.

Fitted in the top of the vessel a is a screwcap h, which may be removedto supply the same with oil or other lubricating-fluid.

Secured about the hub d is an annular sectional ring t', whichis hingedat the base j and attached by short bolts 7c at the top. This sectionalring t is provided with an opening which neatly fits about the conicalbase l), and with an upwardly-extending post Z, formed in- 5o tegralwith one of the sections of the ring lzT.

lubricating-cup to the hub of a pulley.

Rigidly attached on the top of this post Z isa strong spring fm, whichprojects over and 1s in close contact with the screw-cap 7i of thevessel a. This sectional ring i is provided with set-screws n, havinglock-nuts o, which afford a means of rigidly securing the ring 'L' andapparatus connected thereto to the hub CZ of the pulley.

In operation the lubricant is placed in the vessel a and the screw-cap hplaced -in position, the sectional ring 'i vbeing placed on the hub d,and secured thereto and allowed to remain a permanent xtnre. The pointor apex of the conical portion b is inserted into 1 the openings of thering and hub d and the cap h pressed beneath the spring m, whlch securesthe same in. position; The rotary movement of the pulley will operatethe ballvalve g by gravity and permit a small quantity of oil to iow tothe axle at each revolution. lThis ball-valve g may be rigidly attachedtothe stem f, and the said stem f placed in bearings and capable of aslight movement in the direction ot` its length.

*At Fig. 3 on the drawings I have shown a modified means for attachingthe above-described lubricator in position, in which the sectional ringc' is dispensed with and in its place a sectional bar p is used, whichmay be elongated by means of a threaded telescopie portion and locked atany desired length by a jam-nut q. This rod p is provided with sharpenedpoints r, one of which is slightly sunk into the hub d and the otherinto the inner surface of the rim t of the wheel.

To secure the vessel d, a spring u, having a collar w, is looselyattached to the lower section of the rod p and held in position by aset-screw fw.

Having thus described my invention, I claiml. In alubricator for loosepulleys, the combination of a fixed rod attached tothe hub ot' a pulleyand provided with an arm, and the lubricant-containing vessel arrangedbetween the hub of the pulley andsaid arm,

substantially as shown and described. y

3. A lubricator for loose pulleys, compris ing the sectional ringprovided with a hinge connection on one side and means for attachingsaid ring to the hub of a pulley,the rod attached to the sectional ring,the springfarm secured to the upper end of said rod, and the 15 valyedlubricant-containing vessel arranged' between the hubof the pulley andsaid springarm,.substantially as shown and described.

4. A lubricator for loose pulleys, comprising an attaching-ring, a rodrigid with said ring, and a valved lubricant-vessel held in position byspring-pressure between said rod and the attaching-ring, substantiallyas described.

'Intestimony that I claim the foregoing I hereunto affix my signaturethis 19th day of 25 July, A. D. 1890.
